2005 Triumph Speed Triple 1050

CarHunch analysed 106 real MOT records for the 2005 Triumph Speed Triple 1050. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2005 Speed Triple is significantly less reliable than the UK average—only 50% pass on the first attempt compared to 80% nationally—which suggests routine maintenance issues are common on these ageing bikes. The dangerous defect rate sits at a manageable 6.6%, so catastrophic failures are not a widespread concern, but the median MOT score of 50 is a serious red flag.

The average mileage of 11,930 is reasonable for an 18-year-old machine, yet bikes are racking up 0.73 failures and 2.6 advisories per test, pointing to worn electrics, exhaust systems, and brake components rather than engine problems. If you're considering one, budget for pre-purchase inspection and remedial work—these bikes need proper upkeep to stay roadworthy.

What to check before buying a 2005 Triumph Speed Triple 1050

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
